That's the biggest concern I have about recommending keto in general. Dietary supplements aren’t overseen by the FDA, meaning that they’re not evaluated for safety and efficacy in the same way that food and medications are and you may not be getting exactly what you pay for. And if you are? Consuming certain nutrients in supplement versus food form can induce oxidative stress rather than treat it, causing more harm than good to organ tissues. The end result: increased risk of chronic disease, including heart disease and some cancers.
For those looking for something just a little closer to real sugar, you can use Xylitol. It cooks and tastes very similar to sugar, but it has a slight glycemic impact (13 vs. 100 for sugar). It is great, but please keep in mind that it is very toxic to animals and it will raise insulin levels slightly. These are the two most cited reasons for not using Xylitol.
